请教8老师，DS260的问题

我收到了NVC的回复

To process your case, you must first pay any required fees. Then, each applicant accompanying the principal applicant to the United States will need to complete the online IV Application (form DS-260). The IV Application may be partially completed and finished later, or may be completed at one time. However, once submitted, please contact the NVC if you need to update the form.

 

我交费后，需要网上填写DS260。请问DS260是在哪里，我没看到链接。另外问一下，DS260是用于申请人不在美国的情况下的吗？谢谢您。
